    <table><tr><td>
      <p>This page demonstrates using plots within containers that are initially hidden.  Examples are shown for jQuery UI tabs and Accordions</p>
  <div id="tabs">
  	<ul>
  		<li><a href="#tabs-1">Tab 1</a></li>
  		<li><a href="#tabs-2">Tab 2</a></li>
  		<li><a href="#tabs-3">Tab 3</a></li>
  	</ul>
  	<div id="tabs-1">
  	  <p>Tab 2 and tab 3 contain plots which are initially hidden.  Using a combination of alternate sizing specification and the plots "replot" method the plots are properly displayed when their containers are shown.</p>
  	  <p>The alternate sizing specifications for setting plot height and width are needed because a hidden element (or child of a hidden element) has no size.  The first example in tab 2 uses custom "data-height" and "data-width" attributes on the plot target element to specify height.  The second example uses "width" and "height" properties specified on the options object passed into the $.jqplot() function.</p>
    
    <p>The default size is 300px wide by 400px high. The default setting can be overriden by specifying different values to the $.jqplot.config.defaultHeight and $.jqplot.config.defaultWidth properties.  Height and width values are taken in this order of prececence:</p>
      
      <ol>
        <li>The css properties if available and plot is not hidden with display:none.</li>
        <li>Options object passed into the $.jqplot() function.</li>
        <li>Custom data-height and data-width attributes on the plot target.</li>
        <li>The config defaults.</li>
      </ol>
  	  
  	  <p>Here is how the replot method can be used to bind to the "tabsshow" event of the UI tabs:</p>
  	    
<pre>
    $('#tabs').bind('tabsshow', function(event, ui) {
      if (ui.index == 1) {
        plot1.replot();
      }
      else if (ui.index == 2) {
        plot2.replot();
      }
    });
</pre>

<p>The ui.index property is the index of the tab that was shown. </p>
  	</div>
  	
  	<div id="tabs-2">
  		<p>This plot was in an initially hidden container.  It's hieght and width are set by the "data-height" and "data-width" properties of the plot container.</p>
        <div id="chart1" data-height="260px" data-width="480px" style="margin-top:20px; margin-left:20px;"></div>
  	</div>
  	
  	<div id="tabs-3">
  		<p>This plot is in an initially hidden container.  It's height and width are set by the 'height' and 'width' properties of the options object passed into the plot constructor.</p>
        <div id="chart2" style="margin-top:20px; margin-left:20px;"></div>
  	</div>
  	
  </div> 
  
<div id="accordion" style="margin-top:50px">
  
	<h3><a href="#">Section 1</a></h3>
	<div>
		<p>Secion 2 contains a plot.  Sizing plots in hidden accordion sections is very similar to sizing in a tab widget.  Because of the default animation on accordions, however, the plot will not draw itself until the entire accordion panel is shown.</p>
		
		<p>Binidng to the accordion "accordionchange" event is also similar as with tabs:</p>
		
		<pre>
    $('#accordion').bind('accordionchange', function(event, ui) {
      var index = $(this).find("h3").index ( ui.newHeader[0] );
      if (index == 1) {
        plot3.replot();
      }
    });
    </pre>
	</div>
	
	<h3><a href="#">Section 2</a></h3>
	<div>
		<p>
		This plot also has it's height and width set with the data-height and data-width attributes.  Note, if you want the accordian widget to properly size itself </em>before</em> the plot is shown, you must also specify a css height and width on the plot target.
		</p>
		<div id="chart3" data-height="200" data-width="400" style="width:400px; height: 200px; margin-top: 20px; margin-left: 20px"></div>
	</div>
